In modern power distribution, space and efficiency are crucial. The side mounted vacuum circuit breaker (VCB) has emerged as an advanced solution that combines high performance, safety, and compact design. It’s an ideal choice for engineers and utilities looking to optimize cabinet layouts while maintaining the same reliability as traditional circuit breakers.

Degatech Electric, a professional manufacturer of medium-voltage switchgear, delivers cutting-edge side mounted VCBs that ensure superior protection and long-term durability.

Understanding the Side Mounted Design

Unlike the conventional front-mounted design, the side mounted VCB is positioned horizontally or vertically along the side of the switchgear cubicle. This allows engineers to build slimmer and more modular switchgear panels, maximizing the available installation space — a key advantage for facilities where room is limited.

Despite its compact arrangement, the side mounted breaker performs identically to other VCB types, using a vacuum interrupter to extinguish the electrical arc during switching or fault conditions. The absence of SF₆ gas or oil makes it both environmentally friendly and maintenance-efficient.

Core Benefits of Side Mounted VCBs

1. Space Optimization
   The biggest advantage of the side mounted configuration is space saving. This makes it perfect for urban substations, containerized switchgear, or retrofit installations.

2. High Safety and Reliability
   The vacuum interrupter ensures fast arc extinction, minimal contact wear, and high dielectric strength. The sealed structure prevents dust or moisture from affecting performance.

3. Easy Installation and Maintenance
   Side access allows technicians to inspect or replace components without disconnecting the main power bus — improving system uptime and reducing maintenance cost.

4. Long Operational Life
   High endurance in both mechanical and electrical operations ensures a service life exceeding 20 years under normal conditions.

5. Environmentally Friendly
   The SF₆-free vacuum insulation design supports sustainable power distribution goals and aligns with international environmental regulations.

Typical Applications

• Industrial Plants – Power distribution for production lines, motor control centers, and utilities.

• Substations – Medium voltage feeder and transformer protection.

• Renewable Energy – Safe disconnection and control for solar and wind installations.

• Infrastructure Projects – Power reliability for transport, hospitals, and data centers.

In every setting, the side mounted vacuum circuit breaker provides stable, efficient, and maintenance-free protection for medium-voltage systems.

Why Choose Side Mounted Over Traditional Designs

With these advantages, side mounted VCBs are becoming the go-to option for modern compact switchgear used in power utilities and industrial networks worldwide.
